ron'ous MASS.

To all whom it may concern: I

Be it known that I, AxEL U'No SARNMARK, a subject of the King of Sweden,residing at Gottenborg, Sweden, have invented certain new and usefulImprovements in Porous Masses, of which the following is aspecification.

This invention relates to containers for storing explosive gases andmore particularly to the filling or porous mass for such containers andin the accompanying drawing I have shown merely for illustrativepurposes two embodiments of this invention wherem:

' either with great difiiculty or not at all pene trates through tubesor orifices of small diameter. A porous body may be considered acollection of fine tubes or channels. Therefore in order to storecondensed acetylene in steel tubes or tanks without risk these tubes arefilled with briquets of porous material, e. g. asbestos, cork, &c. Thesebriquets have been carefully packed in the open tanks and the lids havesubsequently been firmly screwed or soldered on. More recently, however,a more suitable and far sim ler method has been employed in which whoe-rolled tanks are used that are filled with a plastic or pulverizedmass, which is afterward allowed to dry in the tank. It has, howeverproved that when drying such composition may easily fall asunder, when,in the cracks resulting, acetylene accumulates in quantitiesthat-endanger explosions.

Or perhaps the mass has held during the process of drying, but has notsufiiciently withstood blows or 'jolts afterward.

The present invention avoids all these Specification of Letters Patent.

drawbacks by employing a plastic mass 1 that can be filled into the tank2 through a small hole 3, and afterward, without cracking during thedrying process, it will prove Very durable in every respect. Theinvention consists in the reinforcmg of this mass lwhich may be of anyknown or suitable compositionby mixing into it loose strands of metalWire, for instance, iron wire. This wire could be cut in various orsimilar lengths, e. g. 15 to 20 mm., and entire slabs 5, such as areshown in Fig. 2 to fit into the tank 6, could be made of this reinforcedmass which in every respect is extremely durable. These slabs could alsobe placed in the open tanks, the lids 7 being subsequently screwed orsoldered on, but herein shown attached by screws 8.

Experiments have proved that such a reinforced mass, produced andtreated in this manner possesses extreme durability both during theprocess of drying and, later, as regards jolts during transport, &c.

lVhen employing tanks made in one piece with but a single aperture, themass is inserted through the small hole, after which it is packed anddried. The acetylene intended to be stored in this mass may in the wellknown manner either be dissolved in acetone or other suitable fluid, orbe gaseous. Instead of acetylene any other gas may be stored in the massmade and reinforced according to this invention.

Claims:

1. A porous mass reinforced by short, separated strands of wiredistributed therethrough.

2. A filler for explosive fluid containers including a plurality ofseparately formed bodies each consisting of a porous mass. reinforced bythe admixture of separated strands of wire distributed throughout saidAXEL UNO SARNMARK.
